A real time analog power system simulator for research and teaching has been developed at Delft University of Technology. The simulator consists of 1 swing bus, 7 generators, 2 tap changing transformers, 9 dynamic loads, 12 lines and 12 busbars. Experiments on control of voltage and power-frequency and on steady-state and transient stability are shown.

We present an experimental procedure to measure physical parameters of Ge-alloyed and Si-diffused discrete bipolar junction transistors. By measuring properly both the I–V and C–V characteristics, we determine the doping of the emitter, base and collector zones and also the emitter and collector areas.

In this paper, experience gained in teaching communication protocols at Telecom Bretagne Rennes and at EFP Poznan is reported. Both theoretical and practical teaching aspects are developed. Some of the results presented in this paper are the result of didactic cooperation within the TEMPUS Joint European Project S-JEP 07478-94 “Teaching programme in telecommunications networks”

The paper presents a program for robotics education that runs on standard IBM-PCs under the Microsoft Windows environment. The WinRob package is designed for undergraduate students and emphasises the fundamental aspects of robot modelling and control. The software is self-explanatory and uses menus, dialog boxes and context-dependent on-line help.

New expressions, and a graphical notation are introduced to quantify the effect of zeros on step response characteristics. The expressions, which also hold for non-minimum phase systems, are illustrated geometrically in the s-plane, and give a more accurate insight into a concept of pole dominance than the standard ‘pure-pole’ approximations.

Even though computerised tomography (CT) is a widely used system for medical applications, however, it is still an expensive instrument for use in a common teaching laboratory environment. This paper describes the development of a low cost, laboratory-scale CT instrument based on gamma-rays transmission sensor.

This paper describes the computer aided testing of a digital phase angle meter which can be used for the measurement of phase angle in degrees between two 50 Hz a.c. signals, using the software package MICROCAP IV.
